I will do the competitive advertising, three vendors on the net for this article: Boulanger, Ticketmaster and Amazon. Boulanger website outdated, 28 km for nothing because not available in the store announced on-site vendors unpleasant. Cdiscount more expensive 30 euros with shipping and customer service the worst in the world. Amazon, four days after the tower arrived, no problem, it works well, completely silent, happiness, small, light and processor suitable for everyday use as a family. Not too application at Acer polluting cloud, in short very satisfied.
